The javax.ws.rs.Path annotation specifies the path of a resource. The annotated class is considered as a root resource class when you use the javax.ws.rs.Path annotation at the class level. The annotated method is considered as a sub-resource method or a sub-resource locator when you use the javax.ws.rs.Path annotation at the method level. You can use the javax.ws.rs.Path annotation in:

• A root resource class (class level)
• A public method (method level) annotated by the request method identifier of a resource class (root resource class or sub-resource class): This is a sub-resource method.
• A public method (method level) that is not annotated by the request method identifier of a resource class (root resource class or sub-resource class): This method is a sub-resource locator.
